tLoop in reverse order

Anonymous — Tue, 29 Jan 2019 06:14:04 GMT

Hi,

I am using tLoop component for iteration and gave

from - 3

to 1

step -1

disabled values increasing check box.

I am expecting output as 3,2,1. But, I am getting 1,2,3. Is this how tLoop works? If yes, How can I get my expected behaviour?

Thanks,

Meghana.

|1        |3    |
'---------+-----'

.---------+-----.
|   tLogRow_1   |
|=--------+----=|

iterate - ((Integer)globalMap.get("tLoop_1_CURRENT_ITERATION"))
value - ((Integer)globalMap.get("tLoop_1_CURRENT_VALUE"))
